C = 2×pi×r
72 = 2×pi×r
so r = 36/pi
DE = 30deg×36/pi
DE = (pi/6)×(36/pi) = 6cm
Divide the two numerators and get 3.25 multiply 13 hours by that and the answer to the first part is 42.25
Answer:
17
Step-by-step explanation:
square root of x-1 +5=9
square root of x-1 = 4multiple by power of 2 because square root is cancled by 2.
x-1=16,x=17
Answer: 5¹⁵/₁₆
Step-by-step explanation:
The Wildflower Trail is currently 2³/₈ miles long.
If the city will extend it by 2¹/₂ in 5 years, the length in five years will be;
= 2³/₈ * 2¹/₂
= 19/8 * 5/2
= 95/16
= 5¹⁵/₁₆
2.4 * 1.7....for estimation, round ur numbers to the nearest whole number
estimation : 2 * 2 = 4
actual : 2.4 * 1.7 = 4.08
